Precious metal electrolysis recovery system

Abstract

The invention relates to the technical field of chemical engineering, in particular to a precious metal electrolysis recovery system which comprises a crushing assembly, a reaction assembly, an electrolysis assembly arranged below the crushing assembly, a conveying assembly arranged on one side of the reaction assembly, a first cavity formed in the crushing assembly and a crushing cavity. And a first motor is fixedly mounted in the first cavity, an output shaft of the first motor penetrates through the crushing assembly, extends into the circular cavity and is fixedly provided with a cam, and a sliding rod is slidably connected into the crushing assembly. According to the device, through irregular rotation of a cam, crushing stones vibrate at a high speed, precious metal particles are ground into powder, through arrangement of magnets, an iron block moves in a continuously-changing magnetic field, heating is conducted, then precious metal is subjected to thermal decomposition, nitric acid in an electrolysis assembly is continuously sucked into a reaction assembly through rotation of a rotating rod, and the precious metal is subjected to thermal decomposition. Circulation is achieved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a precious metal electrolysis recovery system. Background technique [0002] The principle of precious metal electrolytic recovery is to use the characteristics of crushed precious metal particles that can be leached under acidic or alkaline conditions, and then go through solvent extraction, precipitation, replacement, and ion exchange in the leaching solution, and finally separate them from electronic waste through electrolysis. recovered in the liquid phase. [0003] The precious metal needs to be leached before the precious metal solution electrolysis, but since the leaching agent of the precious metal can only act on the exposed metal surface, when the metal is covered by ore in its natural state or wrapped in ceramic by application, the leaching agent will It has no effect, resulting in poor leaching effect and low electrolysis recovery rate. [0004] To this en...

[0003] Before the electrolysis of the precious metal solution, the precious metal needs to be leached, but since the leaching agent of the precious metal can only act on the exposed metal surface, when the metal is covered by the ore in the natural state or is wrapped in the ceramic by the application, the leaching agent is harmful to the It has no effect, resulting in poor leaching effect and low electrolytic recovery rate
